Whether you’re shipping domestically or internationally, encountering a delay in the arrival of your goods can disrupt business operations and cause frustration. At Stellar International, we understand the critical nature of timely deliveries and we’re here to help you anticipate and mitigate delays. Read on to discover common reasons for shipping delays and get some practical tips on avoiding customs delays, ensuring your shipments arrive as scheduled.
Understanding shipping delays
Shipping delays can happen for many reasons, affecting various stages of the supply chain. Here are some of the most common causes:
1. Customs clearance delays
Customs clearance is particularly important for international shipping – when goods cross borders, they must be inspected and approved by customs authorities. Delays in customs clearance can happen for several reasons:
- Incomplete or incorrect documentation: One of the most common causes of customs clearance delay is incomplete or incorrect paperwork. Making sure your documentation is accurate to the contents, complete and legible can help you avoid delay.
- Regulatory reviews: Sometimes, goods are subject to regulatory review at the country of import, which can slow down the process. This is common for items like food, pharmaceuticals, and chemicals.
- Import duties and taxes: If duties and taxes are not properly calculated and paid, your shipment can be held up until the fees are settled.
2. Congestion at ports and airports
High traffic at major ports and airports can lead to significant shipping delays. During peak seasons, like the Christmas holidays, queues for your shipment can take longer than expected. Shipping queues can range from a few hours to up to 10 days, depending on the shipping method. It’s crucial to plan ahead and account for these potential delays.
3. Weather conditions
Unpredictable weather conditions can disrupt shipping schedules. Storms, droughts and other severe weather events can cause ocean freight delays and air cargo shipping delays, affecting delivery timelines.
4. Global crises
The COVID-19 pandemic highlighted how global crises can disrupt the supply chain. Restrictions and reduced workforce availability can lead to significant international shipping delays.
5. Carrier issues
Problems with the carrier, such as mechanical failures, labour strikes, or overbooking, can result in delays. Choosing a reliable carrier and maintaining good communication can help minimise the impact of these issues on your business.
6. Customs inspection backlogs
During busy periods, customs authorities can experience backlogs, leading to delays in processing shipments. This is particularly common during major global events like trade shows or international sporting events, when there is a surge in the volume of goods being shipped.
7. Changes in international trade policies
Political and economic changes can impact shipping times. Sudden changes in trade policies like new trade agreements or tariffs can result in delays while businesses and customs authorities adjust to new regulations.
8. Inadequate packaging
Improper packaging can lead to delays if goods are damaged or require additional inspection. Ensuring that items are securely packaged to meet shipping standards can help prevent this issue.

How to avoid customs delays
Customs delays can be particularly challenging to manage, but with careful planning and adherence to best practices, you can reduce the likelihood of encountering these delays.
1. Ensure accurate documentation
Making sure your documentation is accurate and complete is the best way to ensure smooth customs clearance. Key documents can include:
- Commercial invoice: This document should detail the shipment contents, value, and terms of sale.
- Bill of lading: This is a contract between the owner of the goods and the carrier for shipments travelling by sea.
- Air Waybill: This is a contract between the owner of the goods and the carrier for shipments travelling by air freight.
- Packing list: This lists the contents of each package in the shipment.
- Certificates of origin: These may be required to determine the tariff treatment of the goods.
2. Understand and comply with regulations
Different countries have different import regulations. Make sure you understand the specific requirements of the destination country. This includes:
- Restricted and prohibited items: Know what items are restricted or prohibited to avoid clearance delay import issue with your shipment.
- Labelling requirements: Make sure all goods are properly labelled according to the destination country’s regulations.
- Compliance with health and safety standards: For goods subject to regulatory review, check that they comply with local health and safety standards.
3. Prepay duties and taxes
To avoid hold-ups, it is best to prepay any import duties and taxes. This can make the customs clearance process faster and reduce the risk of a customs clearance delay.
4. Choose the right shipping method
The shipping method you choose can impact the speed of customs clearance. For example, air freight generally clears customs faster than ocean freight, but can be more expensive. Using air freight for time-sensitive shipments might be the better option, despite higher costs.
5. Work with a reputable freight forwarder
Partnering with a reliable freight forwarder like Stellar International can significantly reduce the risk of customs delays. Freight forwarders have extensive knowledge of international shipping regulations and can ensure that all documentation is in order and that shipments comply with all relevant laws.
6. Monitor and track your shipments
Use shipment tracking systems to monitor the progress of your cargo. Early detection of potential delays can help you take corrective action promptly. Stellar International provides an online tracking tool to keep you up to date with your shipment.
7. Plan for peak seasons
During peak shipping seasons plan to allow extra time for potential delays. Avoid last-minute shipments and use an expedited service if time is critical.
8. Stay updated on regulatory changes
Staying informed about the latest updates in trade policies, tariffs, and customs requirements can help you proactively address issues before they arise. Subscribing to industry newsletters and working closely with your freight forwarder can keep you ahead of these changes.
